G'day Louis,
The only differences I can see between this and my working
configuration at home is
1/. I have "forward only" rather than "forward first".
So far my DNS providers haven't failed me!
2/. I run named as a non-privileged user. I haven't configured
a complete sandbox (see
http://www.au.freebsd.org/doc/en_US.ISO8859-1/books/handbook/dns.html#NAMED-SANDBOX
for that),
but just did the following:
mkdir /etc/namedb/s
chown bind:bind /etc/namedb/s
chmod 750 /etc/namedb/s
Add the following to the options in named.conf
dump-file "s/named_dump.db";
and named_flags="-u bind -g bind" to /etc/rc.conf.
3/. I don't have the version and query-source lines. I
don't believe they'll break anything for you.
4/. I have set up an authorative "lane.family"
domain for my home network
5/. You may want to add 127.0.0.1 to your listen-on option.
I can't see anything in your setup as is that will wreak havoc on the
internet, but I am not an expert. I would at least run it as bind:bind
rather than root as it is trivial to set up. A complete sandbox is better,
and of course a jail would be even better, but they are both more work.
